Abstract
A compressor includes a cylinder block having a compression chamber therein, a piston arranged in the compression chamber which reciprocates up and down, and a driving mechanism which drives the piston. The driving mechanism includes an elastic member whose peripheral portions are fixed to the cylinder block so as to allow the elastic member to oscillate up and down, and whose center portion is attached to the piston, and one or more piezoelectric actuators that are arranged on the elastic member. In response to a power, one or more piezoelectric actuators repeatedly deform and apply an exciting power to the elastic member.
